v0.4.3 — Intelligent subagents, grep, shell tools, and more

Highlights

  • Subagents: The main AI can spin up parallel agents to research your codebase or execute complex tasks in the background. And big improvements to core tools.
  • Grep tools: Fast code search across your project with ripgrep
  • Shell tools: Run commands with user approval for full control
  • Improved tool calling: Smarter edit flow, strReplace, glob, and unified diff preview
  • Bulk asset import: Import villages, forests, or cities in one batch
  • Import reliability: Assets appear immediately without tab switching

Changes

Added
  • Subagent architecture: Orchestrator delegates to specialized background agents
  • Explore subagent: Rapid codebase discovery with ripgrep and file tools
  • Grep tools for AI code search across the project
  • Shell command execution with user approval
  • strReplace for surgical edits, glob for file discovery
  • importAssets and ImportFromUrlBatch for bulk asset imports
Improved
  • Tool calling: AI chooses the right tool (strReplace vs replaceText vs writeFile)
  • Unified edit preview with accept/reject controls
  • ImportFromUrl uses scan_changes so assets appear immediately
  • Historical chats no longer re-run operations when browsing
  • macOS installer: signed and notarized, export templates bundled
Fixed
  • File reading reliability when working in another tab
